Abstract (en)
[origin: WO9404318A1] A coated abrasive article comprising (a) a porous backing having a front side and a back side; (b) in direct contact with the porous backing, a make coat formed from a composition comprising a radiation curable adhesive applied over the front side of the backing; (c) a multiplicity of abrasive grits bonded by the make coat to the front side of the backing; and (d) a size coat overlying both the abrasive grits and the make coat. The invention also involves several methods for preparing the coated abrasive article. In all of these methods, a radiation curable make coat precursor is applied directly to the front side of the porous backing. No treatment coat is required to seal the backing prior to application of the make coat precursor.
